AB - Abstract
The alignment of polymer chains is a well known microstructural evolution effect due to straining of polymers. This has a drastic influence on the macroscopic properties of the initially isotropic material. In this work, cold forming is performed at room temperature on a tensile testing machine. Polycarbonate films are examined in two loading phases. In the first phase, the specimen is loaded to induce anisotropy, and in the second, it is re-loaded, while the material direction is varied. The investigations are supported by an optical measurement system to gain knowledge about the inhomogeneous material behavior in the initial loading phase and about the anisotropic homogeneous behavior during the re-loading phase. Two dimensional strain contours are obtained from the test data. Additionally, we propose a method for approximation of the macroscopic true stress and compare the results with a common approach based on volume consistency. In the future, the test data will set a basis for parameter identification of constitutive equations taking into account a combination of inhomogenous and homogenous material behavior, exhibiting strain induced anisotropy.

AB - With self-reinforced thermoplastics, it is possible to produce composite systems that, unlike traditional fiber composite materials, do not contain any foreign fibers for reinforcement. Instead, thermoplastic fibers or tapes, for example made of PP or PE, are used in an identical matrix. This opens up a high potential for lightweight construction and, at the same time, very good recyclability.

AB - This study examines the determinants of financial firms' lobbying behaviour in the replacement process of International Financial Reporting Standard 4 (IFRS 4) Insurance Contracts. Based on comment letters in response to International Accounting Standards Board's (IASB) Exposure Draft 2010/8, we investigate firms' lobbying decisions and their long-term lobbying intensity. Using an international sample of publicly listed financial firms, we show that insurance companies and financially constrained IFRS firms are more likely to lobby the IASB. We also examine the long-term lobbying activity in the IFRS 4 replacement process during the years 2007–2010. We find that insurance companies and firms with dispersed ownership lobby more. Our results are stronger for IFRS firms compared to US generally accepted accounting principles users. Overall, we document intense lobbying by financial firms and present results that are largely consistent with economic consequences of anticipated accounting changes being the main driver of firms' lobbying behaviour. These results are in line with prior findings for non-financial firms.
